Daniel 2:39-40

After you will arise another kingdom (Medo-Persia) inferior to you, and then a third kingdom of bronze (Greece under Alexander the Great), which will rule over all the earth. Then a fourth kingdom (Rome) will be strong as iron, for iron breaks to pieces and shatters all things; and like iron which crushes things in pieces, it will break and crush all these [others]. [Dan 7:7, 23]
